function used(Item, Player)
    local Cube = 331142
    local Spawn2 = GetSpawn(Player, Cube)
    if Spawn2 == nil then SendMessage(Player, "You must seek an ancient pond to use this item.", "Yellow") else
    local Distance = GetDistance(Player, Spawn2)
    if Distance > 50 then SendMessage(Player, "You must seek an ancient pond to use this item.", "Yellow")
    else CastSpell(Player, 2550399, 1)
